How do I validate a user login token from my backend?

Use the `validate_login` tool with the user's `uid` and the `access_token` provided by the 4399 SDK. The agent will confirm if the session is legitimate and return the authentication code.

Can I check the status of a specific payment order?

Yes! Use the `query_order` tool with the 4399 order ID. Your agent will retrieve the transaction status, amount, and timestamp from the payment gateway.

Does it support high score submission?

Yes! The `submit_score` tool allows your agent to update the high score for a specific user ID on the configured 4399 leaderboard.
